WOOD SPLINT SHADE 7 Filed Dec. 21. 1929' 5,2527?? Lafby J jl'ffan Patented Oct. 27, 1931 UNITED STATES PATENT OFFICE LEROY J. STEFFEN, OF EVANSTON, ILLINOIS, ASSIGNOR TO HOUGH SHADE CORPORA- TION, A CORPORATION OF CONNECTICUT WOOD SPLINT SHADE Application filed December 21, 1929.

The invention relates to fabric shades the woof elements of which are wood slats and the warp elements are of twine as shown, and its object is to render the shade acid resistant to a degree suiiicient to withstand the acid vapors existing in plating plants, chemical laboratories, manufacturing buildings and other locations where fumes of acids are present in the atmosphere, thereby adapting it for use in such locations.

The invention consists in a shade of this type in which the wood slats are interwoven with warp elements of an acid resisting character, such as wool.

It has heretofore been the practice in the weaving of wood splint shades to use cotton twine as the warp elements. Cotton being sensitive to the action of acids, such shades were impracticable in buildings where the atmosphere is charged with acid fumes, as the threads would be quickly destroyed, permitting the slats to fall apart.

In accordance with the present invention, the warp threads are formed of a fibre such as wool, which is resistant to considerable concentrations of acid in the atmosphere, and in the practice of the invention mohair has been employed with highly satisfactory results.

In the accompanying drawings,

Fig. 1 is a face elevation of the shade; and

Fig. 2 is an edge view thereof.

The shade is composed of a plurality of wood slats or splints 8, the number and length of these slats varying with the size of the shade. The slats constitute the woof elements of the fabric and are interwoven with the warp elements 4 of wool twine, mohair being preferred. The fabric is secured between end plates 5, 6, to which the warp elements are suitably secured. The end plates preferably comprise a pair of thin boards 7 8, between which the adjacent slat elements 3 are clamped, as are also the warp threads.

I claim as my invention:

1. A wood shade having an u er supporting slat, a lower slat, a plurality of cords extending therebetween and a plurality of slats intermediately placed and bound in position Serial No. 415,650.
